I would start with
tar -xvf your_file_name.tar
which will extract the content in the current directory. From then read the INSTALL/README file since instructions depend on many things (version, permissions, system, ...)

Are you using a GUI w/ SuSE or are you trying to use command line only? If you are indeed using a GUI you could install it probably rather simple via YaST. If you are indeed trying to keep command line only then I would go with what ejn74 said.
